All of the foods you mentioned are very good quality. I've fed them all except Primal and Stella & Chewys. The only reason I haven't fed those is because I can't find them in Tulsa. I've heard great things and would like to try them someday.
Chicken is NOT bad. It's just that some pups can develop food allergies to chicken, or any protein, after they've eaten it for a long time. How old are your pups?
I'm currently feeding Acana Pacifica, rotating it with Acana Grasslands. Neither contains chicken so my oldest (who does have an allergy to chicken) can enjoy it. I've been feeding Acana for several months and I'm so impressed with it. I think my munchkins will be eating it for a long time to come.
Have you tried NV's Instinct line? That's a favorite of my pups.
As far as the BEST food to feed.....there isn't one. You have to find one that your babies like, that they do well on and that you're comfortable feeding them. It can be a hard process to find that one food that works for all of you. Good luck!
